How would you code: $r = func() or return 0?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I thought i'd ask for your comments on how you'd code this common perl code with PHP: $value = some_function() or return 0; i usually code my functions to return 0 or "" on error, but have to use the following code to handle it... neither seem like a good solution to me. this way decreses the readability of the code: if (!$value = some_function) return 0; and this way adds an unnecessary if() statement: $value = some_function() if (!$value) { return 0; } -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 7.0.3 for non-commercial use <http://www.pgp.com> iQA/AwUBO7I+l8aXTGgZdrSUEQLW3wCbBhH8w+P+EgJxvs46H9JUtx9q0iUAoKeg pRwrJ6NH230r0EQZl3Wvc5Wl =sUof -----END PGP SIGNATURE-----
